_____________________ is a vascular organ that is formed within the uterine wall
- A. Amnion
- B. Chorion
- C. Placenta
- D. Endometrium
Correct Answer: C
Rationale: The correct answer is C: Placenta. The placenta is a vascular organ that develops within the uterine wall during pregnancy. It serves as a connection between the mother and fetus for nutrient and waste exchange. The amnion (A) and chorion (B) are fetal membranes, not vascular organs, and the endometrium (D) is the inner lining of the uterus where the placenta attaches.
The pregnant patient tells the nurse that she has had three pregnancies and two live births to date. How does the nurse record this in the patient’s history?
- A. Gravida 3, para 3
- B. Gravida 3, para 2
- C. Gravida 2, para 3
- D. Gravida 2, para 2
Correct Answer: B
Rationale: Rationale:
1. Gravida refers to the total number of pregnancies, which is 3 in this case.
2. Para refers to the number of live births, which is 2.
3. Therefore, the correct way to record this patient's history is Gravida 3, para 2.
Summary:
A: Incorrect - para should be 2, not 3.
C: Incorrect - gravida should be 3, not 2.
D: Incorrect - gravida should be 3, not 2.
Middle layer of uterus is called:
- A. Endometrium
- B. Ectometrium
- C. Myometrium
- D. Perimetrium.
Correct Answer: C
Rationale: The correct answer is C: Myometrium. The myometrium is the middle layer of the uterus composed of smooth muscle tissue responsible for uterine contractions during childbirth. The endometrium (A) is the innermost layer responsible for menstruation and implantation. Ectometrium (B) is not a correct term. Perimetrium (D) is the outermost layer of the uterus. Therefore, C is the correct choice as it accurately represents the middle layer of the uterus.
The primary spermatocytes:
- A. are formed by spermatogonia mitosis;
- B. have a complete number of chromosomes;
- C. generate secondary spermatocytes;
- D. are diploid cells;
Correct Answer: D
Rationale: The correct answer is D because primary spermatocytes are diploid cells, containing a complete set of chromosomes (46 in humans). They are formed by spermatogonia through a process called meiosis. During meiosis, the primary spermatocytes undergo two divisions to generate haploid secondary spermatocytes with half the number of chromosomes. Choices A and C are incorrect because primary spermatocytes are formed by spermatogonia undergoing meiosis, not mitosis, and they generate secondary spermatocytes, not the other way around. Choice B is incorrect because primary spermatocytes are diploid, not haploid.
The radius, ulna and humerus forms the ___________ joint.
- A. Knee
- B. Elbow
- C. Ankle
- D. Shoulder
Correct Answer: B
Rationale: The correct answer is B: Elbow. The radius, ulna, and humerus form the elbow joint. The ulna and humerus articulate at the trochlear notch, forming the hinge joint, while the radius articulates with the humerus at the capitulum, allowing for rotation. This combination of movements allows for flexion and extension of the forearm. The other choices, knee (A), ankle (C), and shoulder (D), involve different bones and joints in the body that do not include the radius, ulna, and humerus.
